Valence Definition & Meaning - Merriam-Webster
The meaning of VALENCE is the degree of combining power of an element as shown by the number of atomic weights of a monovalent element (such as hydrogen) with which the atomic weight of the element will combine or for which it can be substituted or with which it …
Valence (chemistry) - Wikipedia
The valence is the combining capacity of an atom of a given element, determined by the number of hydrogen atoms that it combines with. In methane, carbon has a valence of 4; in ammonia, nitrogen has a valence of 3; in water, oxygen has a valence of 2; and in hydrogen chloride, chlorine has a valence of 1. Chlorine, as it has a valence of one ...
